More Madone reviews and also a CAD article about how it was designed:
Mountain Bike – News – News. This is Trek’s first all new OCLV product in ten years and it’s a bike that Trek and Lance have been working on for the last year. The idea was to build a single bike that Lance could race throughout the Tour instead of having one bike for road stages and one for the climbs.
Besides, the “A-stay” seat stays, the new frame shaping is most distinctive on the lower part of the down tube and seat tube. The Madone I rode was outfitted with a slew of bitchen new Bontrager Triple X Lite road components that will be showing up in the fall. Besides the fork (Trek claims even with the alloy steerer the 110 OCLV fork is up to 50 grams lighter than a full carbon fork), there was also the new single-bolt clamp, infinite angle adjust seatpost and some of the new Bontrager wheels which have probably been the biggest labor for Bontrager over the last year. The carbon tubular wheels also use Trek’s own OCLV technology to come in at a claimed weight of 495g front and 695g rear.
“Studiotools allows 5 months design time for Madone”:http://www.caddigest.com/subjects/mcad/select/alias_wavefront_lance.htm. The bike Armstrong rides in the time trial stages took Trek seven months to move from concept to reality in the year 2000. That was a remarkable accomplishment at the time, given that earlier bikes required 12 to 14 months to develop. This year the design team was able to break its own record, creating an all new peloton model, the Madone 5.9, in just five months.
The bike frame saved Armstrong 10 watts of energy, equating to a savings of an entire minute in a 200 kilometer stage race.
